Title: Mnemonic signal device for watch or clock - has generator of luminous or flashing signal giving instantaneous or delayed alarm indication
Inventor: FROELICH EGON DR MED
IPC: G04B47/00
Filed: 1979-01-19
Abstract: For mnemonic purposes a mechanically or electrically operated signal generator is fitted to a watch or a clock. It generates a luminous or flashing signal immediately after switching, or at a preset delay, thus forming an optical alarm clock. The signal is in continuous or intermittent operation until the generator is switched off. The electric system uses either light emitting diodes or a liquid crystal display. In a mechanical system, a coloured symbol appears in the watch, or clock dial, again permanently or intermittently. The optical signal thus replaces the conventional acoustic signals, which enhances its use in a church, theatre, or a conference hall. After switching on, the permanent signal continuously reminds the user of the event to be observed.

Title: Silicone rubber breast prosthesis - with inner stiffening ribs extended beyond cup rim
Inventor: EBERL TERTULIN
IPC: A61F2/50
Filed: 1979-03-27
Abstract: Artificial breast prosteses, to be worn after breast amputations, are often made hollow to reduce the weight and prevent chafing on thescar. If stiffening ribs are added inside the silicone rubber cups to prevent flattening, close contact (during dancing) may cause striction on the skin and dents by suction. This can be eliminated by extending the stiffening ribs beyond the annulus facing the skin so that an air space is created. The silicone rubber is pref. coated by a film of polyurethane.

Title: Locating noise sources in communications channels - compares original and current pulse-echo measurement results and has auxiliary register
Inventor: BUCHTA KARL DIPL ING
IPC: G01R31/11
Filed: 1979-05-08
Abstract: The method and measurement device are for locating sources of noise in communication channels and involves use of the pulse fault location principle whereby reflection times of impulses from noise points are measured and related to position. The pulse-echo method is developed to enable simple reliable detection of unauthorised connections such as tappings in telephone systems. The result of a first measurement is permanently stored as a time (distance dependent) an magnitude echo history for a defined channel. Later measurement results obtained by impulse echo testing the same channel are stored in an auxiliary register. Results of each later measurement are incrementally compared with those of the first measurement. Failure of the stored signals to agree triggers a display having the size and position of the noise source.

Title: Contact pressure measurement in electrical plug connectors - using pneumatic piston displacing test rod and supply pressure measurement
Inventor: BOCK JUERGEN ING GRAD
IPC: G01R31/04
Filed: 1979-10-17
Abstract: The testing and measuring method of the contact pressure of contact springs in spring guides for plug connectors with pins in a given array ensures that all contact springs are tested. The testing can be performed after manufacture or before assembly. Each spring (1) is operated by a test pin (2) on a lever (3) mounted at one end and displaced from its rest position by a pneumatically operated piston. When the lever is raised, a pressure chamber (5) independent of the piston operating pressure but under the same pressure is opened. This occurs when the contact pressure is exceeded and its causes a pressure switch to produce a signal which activates a sensor measuring the instantaneous pressure in the common supply channel (7). This is converted into a value corresp. to the contact pressure.
